I have a requirement where the names of the custom fields far exceed the 40 characters limit. So instead I thought I would put a keyword in the field name and the whole name in the description of the field. Is there possibly a way, to print the description of a field on the VF page? I could have done it manually too but the number of fields is close to 100 and making so many manual entries on the VF page isn't the best approach.
Someone please help!
You can set them via Apex controller. Here is some documentation
So it would be something like this (for hierarchy settings):
Apex:
public String myValueFromPage{get; set;}
public void saveMyValue() {
prefix__MySettings__c settings = prefix__MySettings__c.getInstance();
settings.prefix__myField__c = myValueFromPage;
upsert settings;
}
Visualforce:
<apex:inputText value="{!myValueFromPage}">
<apex:commandButton action="{!saveMyValue}" value="Save Input"/>
if you have setup ant correctly you can follow below steps
Create one package.xml and objects folder
<?xml version="1.0" encoding="UTF-8"?>
<Package xmlns="http://soap.sforce.com/2006/04/metadata">
<types>
<members>xyz__c</members>
<name>CustomObject</name>
</types>
<version>35.0</version>
</Package>
create a xml file inside objects folder and name it with xyz__c.object and put your xml content which you have added as question.
I assume that you have setup ant deploy in build.xml so you can run command ant deploy and it will deploy this object in your target org.

You can fetch the Description but it will require quite some digging into the metadata API. I'd suggest using the HelpText for this and replacing the label for a field by the helptext, which is available directly in VisualForce. E.g.:
